In the increasingly blurred line between streaming music services and the social media business, Spotify has just launched a "follow" button that lets users follow their favorite bands, friends or any profile inside of Spotify. This gives artists the chance to get in on Spotify playlists, albums and songs from their favorite recording labels, publications, musicians or even just friends and social media profiles. Find out more from the Spotify Developer Blog, who said:

"By clicking Follow, users will get seamless and relevant updates within Spotify, including an artist’s latest album, or the perfect pre-party playlist from a favorite magazine or blog. Follow lets listeners get closer to the people whose music they care about."

Social media tools are becoming more widespread as they start to penetrate various other types of mobile app software and music sites. Spotify is smart to get in on that action and spread beyond just being a streaming music site.
